Erwin, thank you again for your quick response. I was blown away by your kindness in helping me solve the issue. I'm a bit of a font fanatic. Well, a crazy font fanatic, actually! Erwin was able to isolate some really wacky fonts that were using too much of Windows resources (hopefully I explained that correctly!). Anyway, he found some fonts that were causing problems for me, and Main Type is working wonderfully, as always. Thank you so, so much! I'm so grateful for your help!!!
